Gross Agricultural Emissions and Unequal Mitigation Pathways in the Brazilian Legal Amazon: Implications for Climate Justice and the Sustainable Development Goals

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate mitigation policies in the Brazilian Legal Amazon have largely focused on aggregate or net emissions, providing limited evidence on how gross agricultural emissions reveal the intensity of productive emission sources independently of carbon removals.

Gender‐Sensitive Resilience in Kyrgyz Households: Latent Profile and Cross‐Lagged Dynamic Panel Approaches

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Resilience is still conceptualised as gender‐neutral in research and policy discussions. However, a gendered resilience framework suggests that gender roles and intra‐household dynamics are intricately linked with household resilience. This manuscript aims to analyse the effect of gender role attitudes on climate change resilience.

Productivity and Human Disturbance Shape Contrasting Distribution Patterns of Core and Occasional Bird Species in a Subtropical Forest Reserve in Southern China

open access: yesIntegrative Zoology, EarlyView.
Bird diversity hot spots in a recovering subtropical forest do not align with protected area zoning, instead occurring in experimental zones with low‐intensity human activity. This mismatch is driven by contrasting responses: Abundant core species are supported by productivity, while many species of low frequency are attracted to the habitat ...

Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

open access: yesAnimal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Bayesian inference for dynamic Q matrices and attribute trajectories in hidden Markov diagnostic classification models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...
